Sapphire Pure Black 990FX Review

Testing:

PCMark 7 is the latest iteration of Futuremark's popular PCMark system performance tool. This version is designed for use on Windows 7 PCs and features a combination of 25 different workloads to accurately measure the performance of all PCs from laptops to desktops.

The two boards trade places at the top by slim margins when tested at stock frequencies. The UD7 however comes out in the lead in every overclock test due to its better overclocking ability.
